The effect of Zr addition on the laser welding of SiCp/2A14Al composite

Zr foil was applied in the laser welding of SiCp/2A14Al composites. The Al4C3 phase and pores was decreased in the fusion zone with Zr addition. The area of fusion zone decreased with the amount of Zr addition. Two new phases (Al3Zr and ZrC) were formed in the fusion zone with Zr addition. Al3Zr was...
